Aluminum die casting is the most common alloy used for the die casting process today, as it is used in a broad range of products. One of the main benefits of aluminum die cast parts is that it is lightweight, yet withstands the highest operating temperatures among all the die cast alloys. Aluminum also has a very high dimensional stability for complex shapes and thin wall applications. Aluminum die casting parts are chosen for their corrosion resistance and good mechanical properties which makes them a primary choice for a wide range of applications from electronic housing to marine applications. Aluminum die cast parts has high thermal and electrical conductivity as well as EMI shielding makes aluminum an excellent choice for enclosures for networking and telecommunication applications as it provides shielding properties while providing effective heat dissipation for the electronic components housed inside. The lightness of aluminum die cast parts makes them an ideal choice for handheld applications such as power tools and other portable devices and is also used extensively in automotive and aerospace applications for weight reduction and fuel efficiency. Aluminum die casting parts are also easy to machine for high precision requirements and can be chromated, anodized, painted or powder coated without difficulty.

According to the statements above, aluminum alloy has characteristics below:

Die casting could be both simple and complex. Die casting generally uses zinc, aluminum, magnesium, copper, lead, and tin, and now zinc die casting is more widespread.

When it compared to other manufacturing process, die casting could be designed according to customer’s preferences and some special requests. Briefly, die casting is a procedure of molding definite that shapes moulds under high pressure.

Why we say it is simple? Because it could be conclude into a few simple steps.
Mold Lubricant is the first step to control temperature. The next step is to insert the molten metal to the die under high pressure. Keeping pressure until the metal is hardened, then stripping moulds from die cavity. Finally, to clean up the mould’s surface.

As die casting products widely used in automobiles, commodities, yachts and other important components, which, everyday, people will get in touch with these products.
Compared to other metal materials, the usage of aluminum casting seems more widely. Some aluminum die casting methods like plaster casting, permanent mold casting and sand casting, are welcomed by the casting manufacturers, for its strengths in fields of price and qualities.
the aluminum casting all can achieve the characteristics of some products, some requirements like certain flexibility, precise size, and individual designs,. And through some practical examples, aluminum casting will be of some less defective and surface defects contrast others.

3, the air hole of magnesium alloy die casting is less than aluminum alloy;
4, magnesium alloy die-casting aluminum is less stick mold, thus saves labor;
5, compared to the aluminum alloy die casting, magnesium alloy has a long mold life span. In good maintenance, the mold can be used more than 250,000 times;
6, compared to the aluminum alloy, when transit from solid to liquid magnesium alloy absorbs less energy;

7, China is a country with abundant magnesium resources, the government encourages the use of magnesium alloy;
8, the magnesium alloy die casting can absorb the vibration, and it is a good choice for the mechanical device to reduce the noise;

Recent years, new alloy die-casting products have been very popular in the market, however, just in the Chinese market. It does not mean it can be so favoured in other countries. So the domestic market is different from abroad. Nevertheless, Luo Baihui, the die casting mold expert, has said that our die casting products can not be going abroad for three reasons:

First of all, there are many shortcomings in using the raw materials which foreign customers cannot accept. What’s more, our country’s die casting production technology is still not perfect. Last but not least, our die-casting mold industry supporting system is not perfect as well.

These points are important obstacles that pressed the globalization of the die casting industry of our country. If we can break through these points, then our hardware products will be reach climax in selling in the international market.

In fact, many people do not know, die and mold are inseparable. Die-casting mold industry comes in to being because they are perfect match.

In the recent years, the third industrial revolution which centered on digital, intelligent and new energy has proceeded at a furious pace all around the world, and which also bring new opportunities for development of the die-casting industry.

With the improvement of die casting product quality demand in the market, the features of die-casting industry was presented in the process.

Now, the main features of die-casting industry are as follows:

First, information and digital lead the development.

Second is to enhance the strength of the intelligent equipment.

Third, the enterprises need to pay more attention of the complex talents and creative talents.

But, all these above are the sufficient condition of die casting enterprises, whether it can make great progress, that all depends on the firm’s own efforts.

Magnesium alloy die casting products have a huge realistic demand and potential demand, which means magnesium alloy will be the industry upstart in the future.

As we all know, china is rich in magnesium resource. Under this optimum condition, the incentive for developers to invest in magnesium die-casting will be inspired.

In recent years, magnesium die-casting grows quickly. The number of Die casting enterprises and R&D institution have expend to about a hundred. In such case, a group of high starting point and high-level enterprise have emerged.

That is to say, the situation of magnesium die-casting has been created. What we need to do is to transform resource advantage into economic advantage, that they can realize their wishes of die casting industrial development.

China’s die casting industry has gone through four generations in the past sixty years. Especially in the recent twenty years, die casting industry is entering a period of rapid growth-the production of which has kept an annual growth of 13 percent.

Now, aluminum alloy is the main types of die casting alloys, but, it can be expected that magnesium alloy die casting parts will have an apparent growth in the next few years.

1) The rapid growth of automotive industry promises to enable die casting industry to have a further development, within the overall context of auto-lightening.

2) Consumer electronic industry has entered an overall universalizing period of smart phones and tablet computer. Because of the consumer demand of slim, light and large screen, these problems prompt the search for solutions, and people find that aluminum alloy and magnesium alloy castings can just meet all these requirements, and this new trend has already established.

Plastics is everywhere in the past few decades. The usage of metal has gradually replaced with plastic products, just like some auto parts, commodities, and so on. While, the products manufactured through the die casting process, and die casting products are usually more durable, when it is compared to other plastic products.
Whether for products designers, or the manufactures, die casting is a fine choice. Die casting is more suitable for precision parts making. And why is the die casting so durable? In addition to durable materials, die casting parts could resist higher temperatures, or other poor conditions.
Die casting parts and plastic parts, both of them are the outcome of different economic development phase, and perhaps in the near future, die casting will be replaced with a new manufacturing methods.

The development ofdie casting industry is always kept pace with automobile industry. During these years around 2000, the automobile die casting usually takes absolute majority of the entire die casting supplies, which always vary from 48 percent to 80 percent.

Of these countries, auto industry in Australia has relied heavily on die casting industry, and America has account for 48 percent, the rest of these auto industry counties are above 50 percent.

As is reported, the proportion has already reached to 75, and which will continue for the next few years. Thus it can be seen that die casting industry has accounted for a very important position in modern industry, so does china.

And now, except the common die casting, such as aluminum alloy and zinc alloy die-casting parts, Magnesium alloy and copper alloy die casting have become more widespread.
